Acid garden soil complex improver

Abstract

Disclosed is an acid garden soil complex improver. The acid garden soil complex improver is prepared from, by weight, 30-50 parts of straw powder, 15-20 parts of shuck powder, 40-60 parts of polyacrylamide, 10-20 parts of sodium alga acid, 15-20 parts of mineral substance, 3-5 parts of microbial flora compositions, 10-15 parts of plant auxiliaries, 3-5 parts of metal chelator, 15-20 parts of ammonium chloride, 5-10 parts of urea, 30-45 parts of sodium humate, 25-30 parts of compound sodium nitrophenolate, 15-20 parts of calcium superphosphate, 10-20 parts of lime, 10-15 parts of activated carbon, 25-35 parts of bamboo charcoal, 15-25 parts of sea mud, 15-25 parts of sawdust, 5-10 parts of plant ash, 10-12 parts of polyhexamethylene guanidine and 8-10 parts of animal waste. The benign micro-ecological environment in the plant soil can be promoted, nutrient absorption and conversion of plant are promoted, the soil granular structure is improved, meanwhile, breeding of harmful pathogenic bacteria is restrained, the content of toxic metal inside soil can be decreased, the water retaining effect is good, and the cost and water resources can be saved.

Description

technical field [0001] The invention relates to an acid garden soil compound improver, which belongs to the technical field of soil improvement. Background technique [0002] With the emission of vehicle exhaust and industrial sulfur dioxide, air pollution has been caused, and over the years, farmers have overused various fertilizers such as nitrogen, phosphorus, and potassium, resulting in various soil compactions and high acidity, which are difficult for plant growth and even cause plant death. . [0003] Soil acidification is a manifestation of soil degradation, which refers to a natural phenomenon in which soil acidification increases and becomes strongly acidic or extremely acidic. Soil acidification in my country is becoming more and more serious, and the acidified land area has expanded to more than 35% of the cultivated land area in my country, and it often occurs in patches, especially in southern my country. The acidification phenomenon is more serious, and the so...

Problems solved by technology

The existing soil improvers used to improve the soil are mainly organic fertilizers and peat soils are directly applied as soil improvers. Although they can improve the fertility of the soil, they can only temporarily improve the fertility of the soil because they have no water retention function, but they cannot improve the soil. The nature of the soil, the solid-liquid-gas three-phase structure of soil retention, water retention, and ventilation is not ideal, which is not conducive to the growth of plant roots

There are also some acidic soil compound improvers on the market, the main component is a mixture of lime and some minerals or industrial by-products, but most of these improvers contain a certain amount of toxic metal elements, such as lead, cadmium, arsenic, chromium, etc. , there is a problem of pollution to the soil environment
